Periodic Trends

Front

What happens to atomic size as you move across a period in the periodic table?

Back

Atoms tend to get smaller because they have more protons, which increases the positive charge in the nucleus and pulls the electrons closer.

Front

How many valence electrons does a neutral atom of nitrogen have?

Back

5

Front

Identify an element with similar chemical properties to oxygen and selenium, with an atomic number greater than krypton but less than iodine.

Back

Tellurium

Front

Which element has a larger atomic radius than Zinc?

Back

Strontium

Front

What do metals have the largest of in the periodic table?

Back

Atomic radius only.

Front

What is the trend in electronegativity as you move across a period from left to right?

Back

Electronegativity increases as you move from left to right across a period.

Front

What is the trend in ionization energy as you move down a group in the periodic table?

Back

Ionization energy decreases as you move down a group.

Front

Define electronegativity.

Back

Electronegativity is the ability of an atom to attract electrons in a chemical bond.

Front

What is the relationship between atomic radius and ionization energy?

Back

As atomic radius increases, ionization energy decreases.

Front

Which group of elements is known for having a full outer shell of electrons?

Back

Noble gases.
